Abstract:

We describe a multi-disciplinary, fundamental study of the design of a class of catalytic materials that utilize sunlight to 1 enable delivery of fuels hydrogen and fuel feedstocks methane, methanol to the Navy using water and carbon dioxide as starting materials or 2 efficiently degrade toxic contaminants, including organophosphorus compounds. Solar-driven photocatalytic water splitting and reduction of carbon dioxide are two of the highest payoff pathways to carbon-neutral fuels. Additionally, adding sunlight-driven photocatalytic activity to adsorptive and degradative materials can enhance decontamination capacity.
